When the battery is applied to the electric device, the battery is usually installed on a mounting seat of the electric device, and the mounting seat is used for providing support for the battery and realizing the electric connection between the battery and related functional modules in the electric device.
The inventor finds that after the battery is mounted on the mounting seat of the electric device, the structure of the mounting seat of the electric device and the assembly mode of the mounting seat and the electric device are systematically analyzed and studied after the problem that the probability of damage of the mounting seat to the supporting structure of the battery is large. As a result, it has been found that, after the battery is mounted on the mount pad, the mount pad supports the battery in a cantilever manner, and in the process of using the electric device, loads such as impact and vibration received by the battery are transferred to the mount pad, and the mount pad supports the battery in a cantilever manner, so that the mount pad bears a relatively large bending load, and thus, the bearing capacity of the mount pad is greatly reduced, and under the action of frequent loads such as impact and vibration, the mount pad is prone to risk of bearing failure and even damage, so that the service life of the mount pad is seriously affected, and the risk of disengaging the battery from the mount pad is initiated.
Based on the above problems found by the inventor, the inventor improves the structure of the mounting base, and the technical scheme described in the embodiment of the application is applicable to the mounting base and the electric device using the mounting base.

After the battery 2 is mounted on the mounting base 4, the battery 2 is directly supported on the lock shaft 431 of the lock mechanism 43, the lock shaft 431 is supported between the first support base 421 and the second support base 422 of the support assembly 42, and the support portion of the lock shaft 431 for the battery 2 is located between the first support base 421 and the second support base 422. In this way, the locking shaft 431 effectively supports both sides of the supporting point of the battery 2, which corresponds to the double-point supporting of the locking shaft 431, and compared with the cantilever supporting of the locking shaft 431, that is, the technical scheme that only one side of the supporting part of the battery 2 is effectively supported and the other side is suspended by the locking shaft 431, the double-point supporting mode of the supporting component 42 to the locking shaft 431 can enable the locking shaft 431 to bear smaller bending load under the same impact, vibration and other load.
The first supporting seat 421 and the second supporting seat 422 respectively have a supporting surface, specifically, the supporting surface is a surface matched with the locking shaft 431, and the supporting surface can be a plane, a curved surface or a cylindrical surface, and can be selected according to practical requirements. The first support seat 421 and the second support seat 422 may be provided independently in the seat body 41, or may be integrally connected to each other and then provided in the seat body 41.
The locking shaft 431 may be disposed through the sealed structure of the battery 2, for example, through a sealed cylindrical surface of the battery 2, or may be disposed through the semi-sealed structure of the battery 2, for example, through a semi-sealed semi-cylindrical surface of the battery 2, which may be specifically selected according to practical needs.
Alternatively, a locking member 22 may be provided on a side of the battery 2 near the mount 4, and a locking shaft 431 may be provided through the locking member 22 of the battery 2.
The support of the lock shaft 431 to the battery 2 may be line contact or surface contact. The distance between the first support seat 421 and the second support seat 422 may be the same or different from each other in the support position of the battery 2 by the lock shaft 431. It can be appreciated that when the supporting position of the locking shaft 431 on the battery 2 is located between the first supporting seat 421 and the second supporting seat 422, bending moments born by two sides of the locking shaft 431 are relatively close, so that under the same external load, bending load born by the locking shaft 431 is minimum.
According to the mounting seat 4 provided by the embodiment of the application, the supporting assembly 42 comprises the first supporting seat 421 and the second supporting seat 422 to jointly support the locking shaft 431, and the supporting position of the locking shaft 431 to the battery 2 is arranged between the first supporting seat 421 and the second supporting seat 422, so that under the same load effects of impact, vibration and the like, the bending moment born by the locking shaft 431 is smaller, the bearing capacity of the locking shaft 431 is improved, and the service life of the mounting seat 4 is further prolonged.
The first bearing seat 421 and the second bearing seat 422 may support the locking shaft 431 in a surface contact, a line contact, or the like, and for example, a contact portion of the locking shaft 431 with the first bearing seat 421 or the second bearing seat 422 is cylindrical, and then a portion of the corresponding first bearing seat 421 or second bearing seat 422 may be a plane, a semi-closed semi-cylindrical surface matched with the locking shaft 431, or a closed cylindrical surface matched with the locking shaft 431, or the like. The method is not limited herein, and can be selected according to actual requirements.
In some alternative embodiments, as shown in fig. 7, the first support seat 421 has a first support hole 421a, and the first support hole 421a is used to pass through the locking shaft 431.
It will be appreciated that during operation of the power device, the impact and vibration load applied to the battery 2 may be directed in various directions, and thus the load applied to the locking shaft 431 and the first support seat 421 by the battery 2 may be directed in various directions. By providing the first support seat 421 with the first support hole 421a, the first support seat 421 can bear loads of the locking shaft 431 in all directions of the first support seat 421, so that the load bearing capacity of the mounting seat 4 can be further improved.

The inclined section 4311 of the locking shaft 431 is matched with the wedge 221 of the battery, so that the specific extending length and distance of the locking shaft 431 can be set according to actual needs in the process of penetrating the locking shaft 431 into the battery along the extending direction, and good matching of the locking shaft 431 and the battery can be ensured. Thus, the requirement on the machining precision of the mutual matching part of the battery and the locking shaft 431 is reduced, and the production cost is reduced.
